Historical Versioning of ELY Areas 2023 (1:1,000,000 Scale) Data Table

The 'table__history' is a rich repository of version history data, meticulously organized as part of the 'tilastointialueet_ely1000k_2023' dataset collection. This table serves as a historical archive, preserving each version of its base table rows, which pertain to the ELY areas 2023. The data is sourced from the website of Statistics Finland (Tilastokeskus). Each row in this table is uniquely identified by a combination of a '_start_date', which marks the date of extraction from the source, and a '_row_number', indicating the row's position in the raw data.

The table also includes an '_end_date' column that signifies when a new version of the row was extracted, helping track changes over time. If this column's value is null, it implies that the row is the most recent version.

An integral part of the table is the geographical information, which is captured in columns starting with 'geom_'. This information, presented using the WGS 84 coordinate reference system (longitude first, followed by latitude), opens up possibilities for geospatial data analytics.

Additionally, the dataset also carries crucial information about the ELY areas, such as their names in different languages, identifiers, and specific geographic attributes. The table also includes a time element, with data corresponding to the year 2023.

The data in this table can be employed in various data analytics applications. For instance, the version history could be used to track changes in the ELY areas over time. Geospatial information could be used to analyze patterns or trends in these areas, or to visualize the data in a spatial context. The multilingual data could be used to create region-specific reports or insights in different languages.
